It's a slippery slope when taking meds that lower the immune system, because it can lead to increased likelihood of getting an infection. In general UTIs I know when I have had them are not pleasant to live with. They can be very uncomfortable and painful too. Then add in having to miss the infusion.
There was a period of time I was getting frequent UTIs also. Experience seems to be the similar with how my body reacted to the infection and lack of the RA meds. I don't get them as frequently now, even though I continue to take the RA meds. For me I started taking a really good pharmaceutical strength probiotic.
Also, I am really glad that you reached out. These are not easy things to walk through. Having walked through something similar I can tell you, you will get through this. Stay in touch with your doctors regarding your symptoms. If you haven't had the discussion with your doctor, ask if there are some ways they recommend for you to help your body to prevent the frequency of your UTIs. Like I mentioned probiotics, increased water intake, and some dietary changes have helped me tremendously.
